Adjunctive Orthodontic Treatment with Lingual Orthodontic System
(Kathmandu University, 2011) Kafle, D; Humagain, M; Upadhaya, C
ABSTRACT The lingual orthodontic therapy though started in 1972, could not be popular till the beginning of 1990. In Nepal it does not have a history of more than a year. It is started in Dhulikhel Hospital for the first time in Nepal. Usually orthodontic therapy is meant for putting braces on the labial surface of the teeth which is called labial orthodontic system. Lingual orthodontic system is a purely invisible kind of orthodontic therapy in which braces are placed behind the teeth. The advantages of lingual orthodontic therapy are: invisibility, better biomechanics and improved patient compliance. On the other hand it is difficult to master and costlier than labial orthodontics. We have presented six adjunctive orthodontic cases treated by lingual system with the same end result comparable to labial orthodontic system. KEY WORDS invisible, labial ,lingual, orthodontics
Anticipated Pain and Pain Experience Among Orthodontic Patients: Is there any Difference?
(Kathmandu University, 2012) Kafle, D; Rajbhandari, A
ABSTRACT Background Orthodontic treatment is taken as a painful procedure by most of the patients. The pain can be experienced during different procedures like separator placement, banding, bonding, extraction as well as arch wire activation and debonding. There are very few studies done on the anticipated pain and pain experienced among mentioned orthodontic procedures. Objectives To compare the anticipated pain and pain experience among the patients going for comprehensive orthodontic treatment. Methods Total 45 patients going for comprehensive orthodontic therapy are enrolled into the study. They are given a 100mm Visual Analogue Scale (VAS) for pain. The anticipated pain as well as perceived pain after different orthodontic procedures are recorded on the VAS by patients and returned back to orthodontic office. The data are analyzed by SPSS 16.00 software by paired and independent t-test for the statistical significance. Results The result showed that there is significant difference between the anticipated pain before orthodontic treatment and the pain experienced following orthodontic treatment. It also showed that perception of pain between two sexes is significantly different. The comparison of anticipated pain among male and female does not show any significant difference, however the pain felt after separator placement as well as after orthodontic bonding is significantly different in two sexes. Conclusion The level of anticipated pain before orthodontic treatment is higher than the real pain experienced after orthodontic procedures. So it is better to counsel and explain the patients about the orthodontic treatment and procedures. KEY WORDS Anticipated Pain, Orthodontic, Visual analogue scale
Gender Based Comparison of Gingival Zenith Esthetics
(Kathmandu University, 2016) Humagain, M; Rokaya, D; Srii, R; Dixit, S; Kafle, D
ABSTRACT Background The size, proportion and gingival zenith position of maxillary anterior teeth plays in the anterior teeth esthetics. Objective To compare the gingival zenith positions and levels between male and female in right and left side as an esthetic parameter. Method Impression of the maxillary arch was made in each participant with irreversible hydrocolloid, and dental cast was made with dental stone type IV. Two clinical parameters were evaluated: (1) the gingival zenith position (GZP) from the vertical bisected midline along the long axis of each individual maxillary anterior tooth; and (2) the gingival zenith level (GZL) of the lateral incisors in an apical-coronal direction relative to the gingival line joining the tangents of the GZP of the adjacent central incisor and canine teeth under healthy conditions. Statistical analyses were conducted using SPSS with the level of significance (α) = 0.05. Descriptive statistics was done and Independent t-test was used to compare the GZP and GZL between male and female. Result In male, the gingival zenith position for right side central, lateral and canine were 1.05 mm, 0.57 mm and 0.14 mm, and in left side were 1.02 mm, 0.53 mm, 0.15 mm. In female, the gingival zenith position for right side central, lateral and canine were 0.99 mm, 0.48 mm and 0.15 mm, and in left side were 0.94 mm, 0.44 mm and 0.14 mm. The gingival zenith position was significantly different between male and female for both lateral incisors. In addition, significantly different was found for the lateral incisor between right and left side. In male, the gingival zenith level of right and left lateral incisors 0.74 mm and 0.71 mm. In female, the gingival zenith level of right and left lateral incisors 0.76 mm and 0.72 mm. No significant difference was found between male and female for the gingival zenith level of right and left lateral incisors. Conclusion The GZP and GZL obtained from this study can be clinically applied to reestablish the GZP of the maxillary anterior teeth during periodontal surgery; crown lengthening or root coverage procedures.

Orthognathic Surgery for the Correction of Severe Skeletal Class III Malocclusion
(Kathmandu University, 2016) Kafle, D; Upadhayaya, C; Chaurasia, N; Agarwal, A
ABSTRACT Skeletal Malocclusions results from the abnormal position of maxilla and mandible in relation with cranial base. These types of malocclusion are commonly treated by orthodontic teeth movement known as camouflage orthodontics. However severe skeletal malocclusions cannot be treated by orthodontics alone. Such cases need surgical intervention to align the position of the jaw along with orthodontic correction. This procedure is commonly known as Orthognathic Surgery. Orthognathic Surgery dates back to early eighteenth century but became popular on mid twentieth century. Though the prevalence of skeletal malocclusion is more than 1% the treatment facility was not available in Nepal till 2012. Here we present a case of Skeletal Class III malocclusion treated at Dhulikhel Hospital, Kathmandu University Hospital. For this case, double jaw surgery was performed by le-Fort I osteotomy and Bilateral Sagital Split Osteotomy. Orthognathic surgery has been routinely performed at this centre since then. KEY WORDS Bilateral Sagittal split Osteotomy, Le-fort I Osteotomy, orthognathic surgery, skeletal malocclusion
Retrospective Study to Determine Stability of Mandibular Setback Surgery using Bilateral Sagittal Split Osteotomy Technique
(Kathmandu University, 2016) Upadhyaya, C; Chaurasian, NK; Kafle, D
ABSTRACT Background Bilateral sagittal split osteototomy of mandible is one of the most commonly performed orthognathic surgical procedure performed in the mandible. According to hierarchy of stability, mandibular setback procedure is considered to be relatively unstable procedure and chances of relapse are higher. Objective We conducted this study to determine the skeletal stability of mandibular setback procedure using bilateral sagittal split osteotomy technique in Nepalese population. Method Lateral cephalograms of 14 patients who underwent mandibular setback using bilateral saggital split osteotomy were taken pre-operatively (P1), immediate post- operatively (P2) and eight months to one year post-operatively (P3). Cephalometric tracing was done for all the cephalograms. Various parameters of Burstone’s hard and soft tissue, Steiner’s and McNamara analysis were used in the study to determine angular and linear changes following surgery. After tracing the cephalograms, changes between P1- P2, P1-P3 and P2-P3 were calculated. Mean difference in changes between P1-P2, P1-P3 and P2-P3 were compared using paired t test. P value less than 0.05 was considered to be significant. Data analysis was done using SPSS software version 20. Result Mean setback at Pogonion was 3.03 mm whereas at point B were 4.64 mm. Relapse at Pogonion was 0.03 mm and relapse at point B were 0.02 mm. Mean change in point A-Nasion-point B angle was 5.1 degrees whereas mean changes in NA-Pogonion angle were 4.69 degrees. Conclusion There were significant changes in angular as well as horizontal parameters at P2 but there were no significant changes in those parameters at P3. This is a preliminary study that we have carried out at our institution with smaller sample size thus we recommend a study with larger sample size and long term follow up.
